Sample proportion used to estimate a population proportion. o D. Sample median used to estimate a population median. The confidence level is chosen by the investigator. We want our estimator to match our parameter, in the long run. This is one of the reasons why in the definition of the sample variance, instead of dividing by n , we divide by ( n − 1). Another line of two-stage methods is the+ 31. The two main types of estimators in statistics are point estimators and interval estimators.
